. What is scope resolution operator in C++?
Scope resolution operator in c++ is denoted by double colon (::). It can be used:

– when there is a local variable with same name as of global variable
– When a function has to be defined outside a class
– When class’s static variables needs to be accessed
– When a class inside another class has to be referred
– In case of multiple Inheritance

What is a class template?


A class template is used to create a family of classes and functions. For example, we can create a template of an array class which will enable us to create an array of various types such as int, float, char, etc. Similarly, we can create a template for a function, suppose we have a function add(), then we can create multiple versions of add().
